We look at the division of 573648 by 18 
We want to divide 573648 by 18.

Step 1:
18 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 18

On to step 2:
The number 18 fits into 57 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 54 from 57 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 18

Let's proceed to step 3:
The number 18 fits into 33 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 15 after subtracting 18 from 33.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 18

Going ahead to step 4:
156 divided by 18 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
If we take 144 away from 156, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 18

Let's proceed to step 5:
The number 18 fits into 124 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 3186.0
Subtracting 108 from 124 leaves us with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 18

On to step 6:
168 divided by 18 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 31869.0
If we take 162 away from 168, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 18, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 31869.3
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
18 goes into 60 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 31869.33
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 31869.33 with a remaining 0.006.
